A keyboard wedge is a hardware device that distributes information between a computer and point of sale terminal. It plugs into a USB port or COM port, and allows input to be received by a computer’s keyboard. It works transparently between the keyboard and point of sale terminal, and doesn’t interfere with the operation of the keyboard. Software versions of this device can also accept input from serial ports and LAN connections.
A keyboard wedge connects to a measurement instrument, a digital caliper, or a legacy device to provide data. The data is typed into an application by the user’s keyboard. A keyboard wedge’s price ranges from $25 to $180, depending on its size and interface. A recent survey of prices shows that the median cost of a keyboard is $350. This price was updated on June 1, 2019.
A keyboard wedge connects to a serial port or USB. The software allows it to interface with a PC application. The computer will think the data was entered using the keyboard. In contrast, a hardware keyboard wedge reads data from digital gages and sends it to a PC via a USB or a keyboard. The data looks like keyboard data to the current application. This includes Microsoft Excel, Microsoft Access, and other database type applications.
